Where previous methods could only guarantee slow progress toward calculating reliable quantum communication rates, a new analysis demonstrates exponentially faster convergence under surprisingly broad conditions. This work establishes that, for key channel types like those experiencing amplitude damping, algorithms can converge at an exponential rate once sufficient iterations are completed, a result previously unproven. By focusing on local geometric properties near optimal solutions, this research unlocks improved efficiency in assessing how much information noisy quantum channels truly transmit.
